It is the ratio of the speed of light in a vacuum (c) to the speed of light in this medium (v): n = c / v. The bending of a light as it crosses the boundary into a different medium is determined by its refractive index, or how much the light is slowed down in the new medium. We see objects breaking at the boundary between media of different density because of refraction. Light rays are bent, or refracted, because light travels at different speeds in different media. Unless the light ray meets the boundary at exactly 90Â°, the direction of travel will change and the light ray is bent..
